Chartae 4. fol: de Nostra 2da Quadrandi Methodo, 1686

 Item
Identifier: Coll-33/Folio C [206]
Scope and Contents A tranche of workpapers in which Gregory continues to labour on adapting Newton's method of quadrature. He continues to have trouble adapting the basic series, an indefinite integral, to the definite integral defined between O and x.

One paper among these was probably intended for the Astronomiae, showing a body moving in an ellipse.
Dates: 1686

Curva Cragio exhibitur, July 1687

 Item
Identifier: Coll-33/Folio C [205]
Scope and Contents Gregory, probably with Pitcairne at his side, sent these curves to Craige in Cambridge, challenging him to find their quadrature. Thus the writing that is not in Gregory's hand may be Craige's.
Dates: July 1687

De Transmutatione Figurarum, c1688-1707

 Item
Identifier: Coll-33/Quarto A [96]
Scope and Contents A treatment by Craig(e) of transmutation of a particular curve into another.

Secondarily, there is a tabulation of the Measures of the Blood Vessells in Dogs by James Kyll MD at Oxford in 1699, and a Dr Robert Areskine's Measures of the Arterys (human? canine?). There is also a 1707 note about how the French form the chamber of their mortars, and a passing mention of a new proposal on quadrature just brought before the Royal Society.
